Lieutenant Green serves as the personal assistant to Spectrum commander-in-chief Colonel White, and is shown to be an expert in computer programming and electronics. A native of Trinidad and Tobago, he is the only lieutenant among its personnel.

Real name Seymour Griffiths, he spends most of his time in the Cloudbase control room. He assists Colonel White in the execution of Spectrum assignments by accessing data and radio links from a large supercomputer, which he operates from a moveable chair. At White's command, Green can activate the control room's display screen or speak on the base's public address system. Green rarely leaves Cloudbase, although he occasionally mentions how he would relish an opportunity to meet primary Mysteron agent Captain Black "face-to-face". On a rare excursion out of Cloudbase in ‘Lunarville 7’, Lieutenant Green assists Captain Scarlet and Captain Blue to investigate reports of unauthorised construction on the far side of the Moon.

We have faithfully recreated Lieutenant Green here, as a Limited Edition of only 200 figurines, featured in the 'Lunarville 7' episode.
